If you're having trouble updating the device's firmware or the device's light does not solid blue after you update manually, it might be due to the following reasons:

• Device offline-Check if your device's light flashing red, or the status of the device in the eufy Security app. If it is offline, reset the Wi-Fi in your house, or change the Wi-Fi in the eufy Security app by going to Device Settings> General> Wi-Fi Connection. Also, check to make sure the device has a strong and stable Wi-Fi connection.
• Device power off - Check if the device's plug is plugged into the socket.
• Weak Wi-Fi signal - If you find that the device LED flashing red, but the status in the eufy Security app still displays it as updating. It could be the updated status of syncing between the device and the eufy Security app might be affected by the network signal. lf you are not sure whether the update is successful or not, you can check the current firmware version in the eufy Security app >device Settings> General> About Device> Check For Firmware Update.
